Note: Some (Debian & Ubuntu, Fedora, KDE) recommend not installing the xf86-video-intel driver, and instead falling back on the modesetting driver for fourth generation and newer GPUs. See Xorg-Installation, and modesetting. However, the modesetting driver can cause problems such as Chromium.
Also, the modesetting driver will not be benefited by Intel GuC/HuC/DMC firmware.
